I'm new to web development, and I'm currently in the process of building a trip planner. I have an activity div where when you click the plus sign a form slide down to insert the information about this activity. essentially I want to create a div with the entered information in this form every time a user hit submit. I have no idea what is this called, or how it could be implemented, any feedback is highly appreciated.
What you could do is to make a function to dynamically create the elements you want to show to the user and call that function on the submit button's onClick handler.
That could look like this:
function create() {
var parent = document.createElement('div');
parent.className = 'parent';
//you would have a child element for each bit of data the user has input
var child = document.createElement('div');
child.className = 'child';
parent.appendChild(child);
//append the newly created div to your container
var container = document.getElementById('container');
container.appendChild(parent);
}
Then add this to the buttons onclick listener
var button = document.getElementById('button');
button.addEventListener('click', create);
This will have the advantage of being able to be called multiple times if the same user is inputting data more than once.
However if this only needs to be shown once you could just have everything already there but not displayed and set it's display property to 'inline-block' instead of 'none'
If you want you can then use the CSS animation property to slide the div down (or whatever animations you want).
function createDiv(){
var i=1;
var ele = document.createElement("div");
ele.setAttribute("id","DivId"+i);
ele.setAttribute("class","inner");
ele.innerHTML="hi "+i;
output.appendChild(ele);
}
<div id="output" class="out">
</div>
<input type="button" onclick="createDiv();" name="submit" >
Write the html code for the form div. Save it as text in a variable
(var html = "...")
and use jQuery
$("#divId").append(html)

This question already has answers here:
InnerHTML append instead of replacing
(3 answers)
Closed 6 years ago.
i've a div container and a button. Whenever i click the button, an empty textbox is added to the div. Now, my problem is whenever i click the button, the textbox is added, but the values of all others are removed.
The function is made like this:
function addTextBox() {
document.getElementById("txtList").innerHTML += "<input type='text'>";
}
I think it help you:
var child = document.createElement('input')
document.getElementById("txtList").appendChild(child);
You could achieve the same thing as the snippet below:
function addTextBox() {
var input = document.createElement("input");
input.type = "text"
document.getElementById("txtList").appendChild(input);
}
document.getElementById("addTxtBoxBtn").addEventListener("click",addTextBox);
<input type="button" id="addTxtBoxBtn" value="add TextBox"/>
<div id="txtList">
</div>
Why you can't achieve the same thing with innerHTML?
This happens because:
The Element.innerHTML property sets or gets the HTML syntax describing the element's descendants.
While the valueof an ipunt element is not an attribute of the element but a property (please have a look here).
If you want to check it in action, please try the following snippet:
function addTextBox() {
var txtList = document.getElementById("txtList");
console.log(txtList.innerHTML);
txtList.innerHTML += "<input type='text'/>" ;
}
document.getElementById("addTxtBoxBtn").addEventListener("click",addTextBox);
<input type="button" id="addTxtBoxBtn" value="add TextBox"/>
<div id="txtList">
</div>
What is happening under the hood here is that when you append the DOM as text using innerHTML you are simply rewriting that section of HTML. Editing your textList innerHTML will execute a new paint of that element and all information will be parsed again. This means you loose your user interaction.
To update your DOM elements successfully there are methods which enable you to do that. namely document.createElement and document.appendChild.
By appending the DOM element as opposed to concatenating the innerHTML(text) your are forcing a limited paint of the specific area. This leaves the rest of the DOM in tact.
Your code here
function addTextBox() {
document.getElementById("txtList").innerHTML += "<input type='text'>";
}
Becomes more like the following
function addTextBox() {
var textEl = document.getElementById("txtList");
var input = document.createElement("input");
input.type = 'text';
textEl.appendChild(input);
}
When you change append to innerHTML as a string, another string gets created (they are immutable). Browser than has to re-render the whole thing.
The other answers show appendChild, but since in your original question you used a string, maybe you want to keep doing so. If that's the case, you can use insertAdjacentHTML with 'beforeend' as first argument.
document
.getElementById('button')
.addEventListener('click', () => {
document.getElementById('txtList')
.insertAdjacentHTML('beforeend', '<input type="text">');
});

I'm trying to get text to show up in a div by using
function frenchBread(){
var div = document.getElementById("orderBox");
div.innerHTML = div.innerHTML + "French Bread";
}
I have created an inpute type = image that will use this function with an onclick event. It works, however, the text shows up in the div for a second then disappears. I'm not sure if this problem is relevant to the fact that this div is inside of a table, too. Sorry, I'm somewhat of a newbie at javascript and html.
<td>
<div class = "order">
<p>Your Order:</p>
<p id = "orderBox"></p>
</div>
</td>
The above is the part of the table that the div is in.
<input type = "image" class = "items" src ="FrenchBread.png" value = "frenchBread" onclick = "frenchBread()">
The above is where I called the function.
An image input is a server side image map. Clicking on it will submit the form it is in. This will cause a new page to be loaded.
Use a button instead.
<button type="button" onclick="..."><img ...></button>
Apply CSS to remove any borders and background colour as desired.
I am aiming to add a button to the screen through the click of another button.
I can successfully add them but they are blank (i.e, No text).
I tried setting the value with this technique:
addButton.setAttribute("value", "Click Me");
This failed, the strange thing is I was able to successfully set the
elements ID with the setAttribute function.
I then tried the following:
var x = document.getElementById("buttonId");
x.value="Click Me";
The above caused the button not to add at all.
Maybe I'm missing something but I can't think why the first method
wouldn't work.
Note: These buttons are all created on the fly so the standard:
<input type="button" value="click me"/>
won't suffice.
Any help appreciated.
function addButton(elementId, value, name, type) {
//Create an input type dynamically.
var element = document.createElement("input");
//Assign different attributes to the element.
element.type = type;
element.value = value; // Really? You want the default value to be the type string?
element.name = name; // And the name too?
var foo = document.getElementById(elementId);
//Append the element in page (in span).
foo.appendChild(element);
}
Try this.
Example fiddle: http://jsfiddle.net/kailashyadav/4Q8Fd/
Here is the code for a button, associated jsfiddle:
$('#createButton').on('click', function () {
var button = document.createElement('button');
button.innerHTML = 'hello';
button.setAttribute('type', 'button');
$('#placeForButton').html(button);
});
Note I set the innerHTML, because an input relies on a value attribute, a button relies on an open and closing HTML attribute. Therefore, the value in between the tags is what sets the button text. This translates into innerHTML.
I only used JQuery to bind an event to the button click.
I've got a simple application that requires a DIV to be clicked, and in turn it shows another DIV which needs to have its content updated.
There are around 40 items that will need to be clickable and show the correct label for each.
Here is what I need to happen...
User clicks a DIV (drag_me)
Information box DIV is then shown (flavour_box)
the default word 'Ingredients' is swapped out with the content from the "flavour_descrip" div
Also update the 'choc_flavour' div with the name of the ingredient (choc_label)
The data comes from a database, so I'm unable to set individual ID's.
I had a similar issue with draggable's, but that was fixed, and I've tried doign somethign similar to no avail.
Here is the clickable DIV (flavour_descrip is set as hidden in the CSS)
<li class="drag_me">
<div>
<img src="RASPBERRY.png" />
</div>
<div class="choc_label">
Raspberries
</div>
<div class="flavour_descrip">
Our description will appear here for the DB
</div>
</li>
Here is the HTML for the popup box...
<div id="flavour_box">
<p class"flavour_description">Ingredients</p>
<div class="flavour_add">Add To Mixing Bowl</div>
</div>
Here is the jQuery snippet for the click (i've commented out the code I had started to rejig, but essentially I need to change the draggable.find to something that will work!)
$(".drag_me").click(function () {
//var htmlString = ui.draggable.find('.choc_label').html();
//$('.choc2_flavour').text(htmlString);
// update the description of the item
//var htmlString = ui.draggable.find('.flavour_descrip').html();
//$('.flavour_description').text(htmlString);
// on click of jar make box pop
$("#flavour_box").toggleClass("visible");
});
Any ideas how I can achieve this?
Added extra question
Now I've had my problem resolved, I need to perform one more task.
Inside the div that gets the details passed using "this", I need to be able to pass one more items to a different piece of script.
The DIV 'flavour_add' is clickable and will need to grab the flavour name to use to update some bits on screen and update a URL on the fly.
<div id="flavour_box">
<p class="flavour_name_label">Label</p>
<p class="flavour_description">Ingredients</p>
<div class="flavour_add">Add To Mixing Bowl</div>
</div>
This is the jQuery I have, but using "this" doesn't seem to work
$(".flavour_add").click(function () {
// hide the ingredient box
$("#flavour_box").toggleClass("hidden");
// show the continue box
$("#added_box").toggleClass("visible");
// get the flavour name
var flavourLabel = $(this).find('.flavour_name_label').text();
// update flavour URL
var _href = $("a.to_step_3").attr("href");
$("a.to_step_3").attr("href", _href + '&flavour=' + flavourLabel);
//$("a.to_step_3").attr("href", _href + '&flavour=TestFromAdd');
// update the mixing bowl list with the ingredient
$('.choc2_flavour').text(flavourLabel);
});
Use $(this) to get the reference to the clicked element:
$(".drag_me").click(function () {
var txt = $(this).find('.choc_label').text();
$("#flavour_box > .flavour_descrip").text(txt);
$("#flavour_box").toggleClass("visible");
});
Besides, there was a "typo" in your html code, replace:
<p class"flavour_description">Ingredients</p>
By:
<p class="flavour_description">Ingredients</p>
You can easily achieve this using jQuery.
$(".drag_me").click(function () {
$('.flavour_description').text($('.flavour_descrip').html());
// on click of jar make box pop
$("#flavour_box").toggleClass("visible");
});
I cannot seem to be able to find the divs for step: 4. Also update the 'choc_flavour' div with the name of the ingredient (choc_label)
I will assume that you mean 'flavour_add' in which case the code should look like this:
$('.flavour_add').text($('.choc_label').html());
Try this:
$(document).ready(function() {
var $flavourBox = $('#flavour_box');
var $flavourDesc = $flavourBox.children('.flavour_description');
var $chocFlavour = $flavourBox.children('.choc_flavour');
$('.drag_me').on('click', function() {
var $this = $(this);
$flavourDesc.html($this.children('.flavour_descrip').html());
$chocFlavour.html($this.children('.choc_label').html());
$flavourBox.addClass('visible'); //toggleClass will remove the class if it is there
});
});
get the text by using "this" (the actual clicked element) and then get the child flavour_descrip div
$(".drag_me").click(function () {
$("#flavour_box").show();
$('.flavour_description').text($(this).find('.flavour_descrip').text());
});
then show the flavour_box div and set the value of the div with the flavour_description class
I have several vertically stacks divs and I want to have a div appear when I click a button within each of these divs. The div that I want to appear will be the exact same for each appearance with the exception of an id associating it with the outer div. How do I do this in Javascript?
I assume I should use the createElement() within Javascript, but how do I append it to the end of a specific element. Also, when creating an element, I have to hardcode the html in the Javascript file. Is there anyway to leave the element within the html design file. I want to seperate design from code as much as possible.
Clone Node
var clone = myDiv.cloneNode();
Example (live demo):
HTML
<div>
<input type="button" onclick="functionClone(this);" value="Dolly"/>
<input type="button" onclick="functionClone(this);" value="Dolly_1"/>
</div>
Javascript:
functionClone = function(subject){
var clonenode = subject.cloneNode(true);
subject.value = subject.value + '\'s been cloned!';
subject.disabled = true;
insertElementAfter(subject, clonenode);
}
insertElementAfter = function(subject, newElement){
subject.parentNode.insertBefore(newElement,subject.nextSibling);
}
To append an element below your div use this:
subject.parentNode.appendChild(clonenode)
